I picked up the Franklin Mini Pickleball Paddle and Ball Set for something to do indoors, and it works exactly as described. You get two 9" x 4.5" paddles and two 1.65" mini balls, so it's ready for two players right out of the set. Any flat surface like the dining table becomes a court, which is great for rainy days or family game night. It's simple to play and easy to pack for the park. Not a serious training tool, but fun for kids and adults who just want a quick tabletop game.
